Hi, I have noticed for three days now not being able to post comments from my Lemmy.world account while connected via Tor (I was left waiting for a spinning wheel )! I thought at first It might be a problem with LW servers but after three days, I concluded they are banning Tor and VPN users from posting, I Have found a user post on their help community about VPN and tor ban.
then I tried signing-up to lemm.ee but was greeted with a couldflare of non ending page reload after solving captcha. so I created this account hoping to test this instance and ask Lemmy users with privacy concerns about where this is headed and should we expect the rest of Lemmy instances to go the way of reddit and entirely ban users behind proxies ?
The fact that very big instances hold the majority of the communities and discussions on lemmy and the fediverse in general is concerning. and adopting tactics like shadow banning and dark patterns is concerning as well. I dropped reddit for the same practices and I will drop Lemmy if it carries on like this.
Just to add some more context, there was an attacker recently who created accounts on several Lemmy instances and used those accounts to spread CSAM. On lemm.ee, this attacker created 4 accounts over a 24h period, but was not able to upload any CSAM to our servers due to our stricter upload rules (we require 4 week old accounts to upload any images at all), and all of the 4 accounts were removed very shortly after creation (most of them within an hour of signing up). The attacker gave up trying to use lemm.ee very quickly, and moved on to other instances.
I just wanted to share this context to illustrate that while indeed the different measures we implement to protect the instance can have a negative impact on legitimate users, I really believe that overall, they have a net positive effect. In addition to Cloudflare DDoS protection and image upload restrictions, we also have a separate content-based alerting layer on top of Lemmy, which allows our admins to quickly notice when something suspicious is going on. As another example, this alerting has allowed us to extremely efficiently deal with a current ongoing spam attack on the Fediverse, and I bet many lemm.ee users aren’t even aware of this attack due to the quick content removal. We will continue to improve our defenses, and hopefully try to limit the impact on real users as much as possible, but some trade-offs are necessary here in order to protect the overall userbase.
